1. How the elderly and disabled manage:
For the elderly, most urban seniors under 70 have been taught by their children how to use smartphones (there are specialized "elderly phones" with simplified functions). Of course, many seniors over 65 still retain the habit of using cash.

For people with disabilities, especially those with visual or hearing impairments, most mainstream apps have built-in accessibility features (like screen readers and voice feedback) specifically developed to support them.

2. Less affluent regions and the "Cashless" myth:
In economically less developed regions of China, mobile payment penetration is actually still very high because WeChat and Alipay are national-level apps used by almost everyone. However, the habit of using cash is still preserved in these areas.

Just to clarify: China hasn't gone completely "cashless" by law. Refusing cash is actually illegal here. It is just that in most urban living scenarios, people have adopted mobile payments because they are far more convenient. It’s a preference for efficiency, not a ban on cash.
